SAFETY: Kimura from Reverse Scarf Hold targets the Shoulder joint, rotator cuff, and shoulder capsule. Risk: Rotator cuff tear (supraspinatus, infraspinatus, teres minor, subscapularis). Release immediately upon tap.
The Kimura from Reverse Scarf Hold exploits the unique body orientation of ushiro kesa gatame to create a powerful shoulder lock with favorable grip mechanics. Unlike kimura attacks from standard side control, the reverse orientation positions your hands naturally aligned with the figure-four grip path, reducing the number of grip transitions needed to secure the submission. The heavy chest pressure inherent to reverse scarf hold pins the opponent flat, preventing the hip escape and frame creation that typically disrupt kimura attempts from other positions.
The mechanical advantage stems from combining crushing top pressure with arm isolation. The opponent’s near arm is already compromised by the positional control, and the attacker can maintain full body weight on the pin while both hands work to establish and finish the kimura. Common defenses like grabbing the belt, straightening the arm toward the head, or rolling away are less effective because the reverse pressure angle changes the escape geometry compared to conventional attacks.
This submission integrates into a broader attack system from reverse scarf hold that includes the americana, arm triangle, and positional transitions to mount or north-south. The kimura threat forces defensive arm reactions that expose pathways to these alternative attacks, making the reverse scarf hold significantly more dangerous when the opponent cannot neutralize the shoulder lock threat.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| Rotator cuff tear (supraspinatus, infraspinatus, teres minor, subscapularis) | High | 3-9 months with potential surgery requirement |
| Shoulder capsule damage and dislocation | CRITICAL | 6-12 months, may require surgical repair |
| Labral tear (glenoid labrum) | High | 4-8 months, often requires arthroscopic surgery |
| Bicep tendon strain or rupture | Medium | 6-12 weeks for strain, 3-6 months for rupture |
Application Speed: SLOW and progressive - 3-5 seconds minimum in training, allowing partner time to recognize danger and tap
Tap Signals:
- Verbal tap (saying ‘tap’ or making any verbal distress sound)
- Physical hand tap (multiple taps with free hand)
- Physical foot tap (multiple taps with either foot)
- Any distress signal including screaming or unusual sounds
Release Protocol:
- Immediately stop all rotational pressure the instant tap is felt or heard
- Return the arm toward neutral position by externally rotating back to starting position
- Release the figure-four grip completely
- Allow partner to self-assess shoulder mobility before continuing
- Never release suddenly or allow arm to spring back forcefully
Training Restrictions:
- Never spike or jerk the submission - rotation must be smooth and controlled
- Never use competition speed or surprise attacks in training
- Always ensure partner has at least one hand free to tap
- Do not apply while partner is in awkward body position that prevents tapping
- Never combine with weight pressure that restricts breathing while finishing
- Respect immediate taps without testing partner’s pain tolerance
Outcomes
| Result | Position | Probability |

Playing as Attacker
Key Principles
-
Maintain heavy hip and chest pressure on the opponent’s torso throughout the entire grip acquisition and finishing sequence
-
Control the wrist first before threading the far arm underneath for the figure-four to prevent arm extraction
-
Use the reverse orientation angle to your advantage by driving the wrist behind the opponent’s back rather than upward
-
Widen your leg base when transitioning from control to submission to resist bridging counter-attacks
-
Peel the elbow away from the opponent’s body before applying rotational pressure to maximize mechanical leverage
-
Treat the kimura as part of a submission chain with americana and arm triangle to force defensive reactions
Execution Steps
-
Stabilize reverse scarf hold control: Confirm your hip bone is planted firmly on the opponent’s sternum with your chest driving down into …
-
Secure near-side wrist control: With your near hand, grip the opponent’s near-side wrist firmly, pinning it against their body or th…

Thread far arm for figure-four: Release your far-side anchor and thread your far arm underneath the opponent’s upper arm from the ou…

Peel elbow away from body: With the figure-four secured, use both arms to lift the opponent’s elbow off the mat and away from t…
-
Adjust base for finishing angle: Step your near leg toward the opponent’s head to create a perpendicular angle to their body. This le…

Apply controlled rotational finish: With the elbow elevated and your base set, drive the opponent’s wrist toward the mat behind their ba…

Finish or transition: If the opponent taps, immediately release all pressure following the release protocol. If they defen…
Common Mistakes
-
Lifting hips off the opponent’s chest while securing the figure-four grip
- Consequence: Opponent bridges freely and escapes to guard or turtle, losing the positional advantage that makes this kimura viable
- Correction: Keep your hip bone planted on the opponent’s sternum throughout the entire grip transition. Use your arms independently while your torso maintains committed weight pressure.
-
Attempting to finish by pulling the arm upward instead of rotating behind the back
- Consequence: Reduced mechanical leverage allows the opponent to resist with arm strength alone, stalling the submission and wasting energy
- Correction: Drive the opponent’s wrist toward the mat behind their back in an arc while keeping the elbow elevated. The finish is rotational through internal shoulder rotation, not a vertical lift.
-
Failing to secure wrist control before threading the far arm for the figure-four
- Consequence: Opponent pulls their arm free during the grip transition, losing the submission attempt and creating space to begin escaping
- Correction: Always establish a firm wrist grip with your near hand first and pin it against their body before releasing your far-side anchor to thread the figure-four.
Playing as Defender
Key Principles
-
Protect the near-side arm by keeping the elbow pinned tight to the ribcage with the hand gripping the opposite shoulder or lapel
-
Recognize the grip transition early and defend before the figure-four is fully connected rather than after
-
Use hip movement and angling to disrupt the attacker’s chest pressure rather than attempting to push them off with arm strength
-
Grip your own body, belt, or shorts to create a secondary barrier against arm separation when the attacker begins isolating the arm
-
Time defensive bridges and hip escapes for the moment the attacker releases positional grips to establish the figure-four
-
Accept the position temporarily rather than panicking and wasting energy on ineffective escape attempts
Recognition Cues
-
Attacker shifts their near hand from positional control to your wrist, indicating transition from pin maintenance to submission setup
-
Attacker’s far arm begins threading underneath your upper arm between your elbow and ribcage to establish the figure-four
-
Attacker’s weight shifts slightly as they release their far-side anchor to commit both hands to the grip sequence
-
You feel your near-side arm being pulled across your own body or your wrist being pinned against your torso
Escape Paths
-
Bridge and hip escape to recover half guard or closed guard when attacker compromises base during grip transition
-
Straighten the arm and pull free from the figure-four before the elbow is peeled away from the body
-
Roll toward the kimura side to relieve rotational pressure and potentially end up in top position if grip breaks
